By any chance are those Vox models manufactured by JMI? If so there is a new book on the market with blueprint style schematics of ALL JMI Vox amps.
I know there are transistor models in the collection but not sure about the amps you are asking about. Search for "Vox Amplifiers, The JMI Years" by Jim Elyea. The book with schematics is expensive but well worth it if you work on Vox amps.
